My 3 year old Walmart branded EverStart automotive battery failed this last weekend. The battery (Model 47-3) came with a 2 year replacement warranty, and a 72 month pro rated warranty. My battery was purchased in December 2005. I was told that their "system wouldn't allow them to honor the warranty." I asked to speak to the store manager. The store manager was unavailable, but the assistant manager told me the same thing. I have written a complaint to the company. Please be aware that Walmart does not honor its extended warranties. read full review »
